[PULL request] md fixes for 2.6.36

Hi Linus,
It turns out there is a regression:
https://bugzilla.kernel.org/show_bug.cgi?id=19642

that was my fault.
The first of these three patches (avoid overflow...) fixes it.
The other two are very small fixes that seem suitable to include at this time.

Thanks,
NeilBrown

Just a confirmation that the patch series (I didn't try them one at
a time) fixes the regression. I'd also like to agitate for inclusion
in 2.6.36.

Thank you very much; this was obviously a slightly obscure bug!
